I am modeling a house design in Sketchup Free (https://app.sketchup.com/app). I have successfully used leader text to label objects in the model. In the past, when I zoomed in or out, the leader text stayed in scale with the model. When I zoomed out, the text got smaller on the screen and the text fields did not overlap.
I have not used Sketchup for several months. Now when I use Sketchup, leader text stays at a fixed size on the screen. When I zoom out the model gets smaller but the leader text stays the same size and the leader text fields get gradually closer together, finally overlapping each other, resulting in a meaningless jumble of characters.

3D text does not have this problem, text size stays in scale with the model.
